Dewalt - DW742 - Electric Flipover Saw

ENGLISH
General handling
- In the mitre saw mode, the sawhead is automatically locked in the
upper “park”-position.
- Squeezing the head lock release lever will unlock the sawhead.
- Never seek to prevent the lower guard returning to its park position
when the cut is completed.
- The minimum length of offcut material is 10 mm.
- When cutting short material (min. 190 mm to the left or the right of the
blade), the use of the optional material clamp is recommended.
- When cutting UPVC sections, a supporting piece made out of timber
with a complementary profile should be placed beneath the material
being cut to provide the correct level of support.
Vertical straight cross cut (fig. S)
• Set the rotating table to 0° and make sure that the locating plunger is
engaged.
• Pull down the rotating table clamping knob.
• Place the wood to be cut against the fence. Take hold of the control
handle and press in the head lock release lever.
• Switch the machine on.
• Allow the blade to cut freely. Do not force.
• When the cut is completed, raise the sawhead to its rest position and
press the red stop button.
Do not allow the sawhead to jump back unaided to prevent
damage.
Mitre cuts (fig. T)
• Set the required mitre angle.
• Ensure that the rotating table clamp is tightly secured.
• Ensure that the depth stop limiter is correctly set to prevent the blade
cutting the table if the angle is not 45°.
• Proceed as for a vertical straight cross-cut.
Bevel cuts (fig. U)
• Release the bevel clamp handle (24) and tilt the head to the angle
required.
• Tighten the bevel clamp handle.
• Proceed as for a vertical straight cross-cut.
Compound mitre
This cut is a combination of a mitre and a bevel cut.
The limitations are 45° mitre/30° bevel. Do not exceed these limits.
• Set the bevel angle and subsequently set the mitre angle.
Sawing in the bench mode
• Always ensure that the riving knife and blade guard are correctly aligned.
Ripping (fig. V)
• Set the blade to the correct height.
• The correct blade position is to have the tips of three teeth above the
top surface of the wood.
• Mount the parallel fence using either the 10 mm or the 62 mm profile.
The piece of wood between the fence and the blade is the retained piece.
• Switch the machine on.
• Slowly feed the timber underneath the front of the upper blade guard,
keeping it firmly pressed against the fence. Allow the teeth to cut and
do not force the timber through the blade. The blade speed should be
kept constant.
Always use a push stick.
• When the cut is finished, switch off by pressing the red stop button.
Bevel cuts (fig. W)
• Release the bevel clamp handle and set the blade to the required angle.
• In order to prevent material jamming between the blade and the fence,
position the fence to the left of the blade.
• Proceed as for vertical ripping.
Mitre cuts (fig. X1 - X3)
• To adjust the mitre fence, loosen the stop screw locknut (90) and
screw the stop (91) in or out until the mitre pointer reads 0° (fig. X1).
• Set the blade height and angle.
• Insert the slide bar (92) of the mitre fence into the groove (93) provided
in the left-hand side of the table (fig. X2).
• Loosen the mitre locking knob (94) and rotate the fence to set the
scale to the required angle (fig. X3).
• Tighten the mitre locking knob (94).
• Place the workpiece against the flat surface of the mitre fence.
Switch on and, holding the workpiece firmly, slide the fence along the
groove to take the workpiece into the blade. When the cut is
completed, switch off immediately.
Fence positions, saw bench mode (fig. Y)
- For ripping thin materials, use the 10 mm profile of the dual height
parallel fence and position the fence opposite the front edge of the
riving knife.
- For ripping thicker materials, use the 62 mm profile of the dual height
parallel fence.
- For cross-cutting narrow and short workpieces (fig. Y):
• Adjust the parallel fence with the low profile facing the blade and
install the rear of the fence in line with the leading edge of the blade.
• Set the workpiece against the mitre fence (at 0° or 90°) and push the
mitre fence to make the cut.
• To prevent small offcut pieces fouling against the blade, prepare a
tapered length of timber and clamp it on the rear edge of the
worktable close enough to the right-hand side of the blade so that
successive offcuts feed automatically to the right.
- For ripping narrow (< 120 mm) and long workpieces:
• Place the fence in rearmost position to maintain accuracy during
long cuts.
• Push the workpiece with both hands (one on each side of the blade).
• Use a push stick when close to the blade.
• Support long workpieces at the outfeed side.
- For ripping wider (>120 mm) workpieces:
• Adjust the fence forward as in figure Y if the material being cut tends
to jam between the blade or the riving knife and the fence.
Optional accessories
Prior to assembling any accessories always unplug the machine.
Dust extraction kit (fig. A1, A2 & A8)
This machine is provided with three dust extraction points for use in each
mode.
• Whenever possible, connect a dust extraction device designed in
accordance with the relevant regulations regarding dust emission.
Connecting - mitre saw position
• Connect one hose to the under-table guard.
• Connect one hose to the small diameter outlet (11) and one to the
large diameter outlet (23) using the corresponding spouts.
• Connect the hoses to the 3-way connector.
• Connect the single outlet of the 3-way connector to the hose from the
dust extractor.
